Online Text Editor

Plain-text editor with find-and-replace (case-sensitive and regex), case conversion (upper, lower, title, sentence), and per-line operations. Per-line operations include trim whitespace, drop empty lines, drop duplicates, sort A-Z or Z-A, reverse, and add or strip line numbers. Live counters cover characters (with and without spaces), words, sentences, paragraphs, and lines, and edits auto-save to local storage with optional .txt download and a Ctrl+Z/Ctrl+Y undo stack.

Documentation

The online text editor combines a plain-text workspace with real-time statistics, find and replace, and a set of case-conversion and per-line transformation tools, all running in the browser with no account or installation. Content can be typed directly or pasted in, from a short note to a full document. Statistics, transformation, and search all operate on the same text at once, so a count, a case change, or a sorted list of lines all apply to the current draft without switching between separate tools. Every change auto-saves to browser storage, so the text survives closing the tab or refreshing the page.

  • Live statistics report character count (with and without spaces), word count, sentence count, paragraph count, and line count, updating as the text changes, useful for meeting limits on social posts, subject lines, or form fields.
  • Find and replace supports case-sensitive matching and regular expressions for advanced pattern matching. Matches can be stepped through one at a time, replaced individually, or replaced everywhere in a single pass, which is faster than working through repeated instances of the same text by hand.
  • Case conversion covers uppercase, lowercase, title case, and sentence case. Per-line operations trim leading and trailing whitespace, drop empty or duplicate lines, sort alphabetically in ascending or descending order without manual reordering, reverse line order, and add or strip line numbers.
  • Text copies to the clipboard directly for pasting elsewhere, or downloads as a .txt file with a customizable filename for saving outside the browser.
  • Settings also toggle auto-save and word wrap, which controls whether long lines visually wrap within the editor or scroll horizontally, useful when working with unwrapped log lines or code.
  • Ctrl+Z (or Cmd+Z on Mac) undoes recent changes, including transformations, find and replace, paste, and reset actions that the browser's native undo cannot reach, since those are programmatic edits rather than ordinary keystrokes. Ctrl+Y or Ctrl+Shift+Z redoes.

Plain-text editing, transformation, and cleanup workflows span writing, development, data preparation, and content production alike. The scenarios below cover common tasks each handles.

  • Writing and Drafting: Draft blog posts, articles, emails, or notes in a distraction-free environment. The auto-save feature ensures that no work is lost during a writing session, even if the browser is accidentally closed.
  • Data Cleaning: Paste a list of items copied from a spreadsheet or database and use the transformation tools to remove duplicates, trim whitespace, sort entries, or remove empty lines. Prepare clean data for import into other systems.
  • Content Editing: Use Find and Replace with regular expression support to perform advanced search and replacement operations across large blocks of text. Correct repeated typos, reformat patterns, or standardize terminology in a document.
  • Code and Configuration: Edit plain text configuration files, code snippets, or log files. Use line numbering to reference specific lines and sort or deduplicate entries in lists or configuration blocks.
  • SEO and Marketing: Prepare keyword lists by pasting raw data, removing duplicates, sorting alphabetically, and trimming unnecessary whitespace. Monitor character and word counts to stay within platform limits for meta descriptions, ad copy, or social media posts.
  • Education: Track word and character counts to meet essay length requirements. Apply the transform tools to prepare example text or format student submissions consistently.
  • Quick Formatting: Convert pasted text to a consistent case format before inserting it into a presentation, document, or form. Title case conversion is useful for headings, while sentence case normalizes text copied from all-caps sources.
  • Reusable Templates: A standard reply, disclaimer, or signature block stays in the editor between visits thanks to auto-save, formatted once and pasted wherever it is needed instead of retyped.
